cellular
|
• mice show increased proliferation and expansion of HSCs after myelosuppressive chemotherapy (treatment with 5-FU), inflammatory stress (treatment with pI:C) and transplantation (increased competitive repopulation capacity)
• untreated LSK cells exhibit a higher colony-forming potential than wild-type cells, with larger and more colonies, which is more pronounced in secondary colony forming units
|
hematopoietic system
|
• mice show increased proliferation and expansion of HSCs after myelosuppressive chemotherapy (treatment with 5-FU), inflammatory stress (treatment with pI:C) and transplantation (increased competitive repopulation capacity)
• untreated LSK cells exhibit a higher colony-forming potential than wild-type cells, with larger and more colonies, which is more pronounced in secondary colony forming units
|
|
• slight decrease in T cells (CD4+CD8+)
|
|
• slight increase in megakaryocytes (CD41+)
|
|
• slight decrease in erythrocytes (Terr119+)
|
|
• slight increase in granulocytes (CD11b+Gr-1+)
|
|
• mice exhibit decreased Lin-Sca-1+cKit+ (LSK) numbers
• however, quiescent hematopoietic stem cell (HSC) and long term-hematopoietic stem cell (LT-HSC) numbers are normal and amounts of myeloid and lymphoid lineages are normal, with only minor differences in T cells and granulocytes
